Claims

[Scope of utility model registration request]

The whole has a flat plate shape, and between the upper surface 11 and the lower surface 12, there is a flat side surface 13 and a substantially concave half-circular surface 14 formed along the circumferential direction in contact with this side surface 13. 2
A notch 15 having a substantially V-shaped cross section and extending from the upper surface 11 toward the lower surface 12 is formed between the side surface 13 of one set and the arcuate surface 14 of the other set. Of the two walls that define this notch 15, the wall on the side 13 side is made a flat surface 16, and the intersection between the upper end of the wall on the arcuate side 14 and the upper surface 11 is cut off. , there is formed a convex curved surface 27 whose one end is in contact with the upper surface 11 and whose other end is in contact with the lower end which is the flat surface 29 of the wall surface on the side of the arcuate surface 14, and this convex curved surface 27 and the upper surface 11 and the arcuate surface 14 A throw-away tip characterized in that a cutting edge 18 is formed on the ridge formed by the side surface 13.
